[jira] [Created] (HDFS-2811) HA: Client should fail if a failover
occurs which switches block pool ID
HA: Client should fail if a failover occurs which switches block pool ID
------------------------------------------------------------------------
Key: HDFS-2811
URL: https://issues.apache.org/jira/browse/HDFS-2811
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, hdfs client, name-node
Affects Versions: HA branch (HDFS-1623)
Reporter: Aaron T. Myers
Making sure that the client is talking to an NN with the same block pool ID as the one it was previously talking to seems like a good sanity check.

[jira] [Resolved] (HDFS-2811) HA: Client should fail if a failover
occurs which switches block pool ID

Brandon Li resolved HDFS-2811.
------------------------------
Resolution: Invalid
As it was pointed out, the client should not be aware of the block pool ID, and even it did, the verification on client side is hard to be fool proof. Close it as not a problem.
